I am reluctant to reinstate discussions on resistance.
I have always thought of a ballist resister as a shock absorber. It allows higher current when needed and reduces current when not needed.
I am guessing that the main purpose of a ballist resistor was and is to extend the life of your coil. Once your engine is up and running it requires less current to run properly, and when cranking an engine the starter takes a lot of the current.
I am also guessing here, but I always thought that a coil fails from overheating. Those fine little winding wires get too hot and their coating breaks down and they short out, or the little wire actually breaks. I always figured that an intermittant coil has a broken wire that touches together when cool and then looses its connection when it heats up. The intermittant ones are the ones that drive me crazy. I also had a spark plug that did that once. It was fine for just a minute or two and then stopped working. Drove me nuts...
